p In France May 23, 1942 v"'fseeun 1, Public Law 690, A111111@t 1946 n y lPatent expires May 23 1962 My invention has for its objecta new arrangement for the frames of machine tools and especially of drilling machines and itsl main aimv is thesimplication of the removal of filings and liquids used for sprinkling the drilling endv of the tool.

In such a frame there `isv a clear upper surface between the slides Yandwithin this area are'located inclined surface portions into-which theY filings and sprinkling liq-uidsdrop. vAt the lowermost point of this inclined surface portion a discharge opening is arranged with an outlet into a passageway within. the. framey through which the filings are removed. ,Within the frame there isa sloping channel having a slight vslopeA and designed so as to allow the lidui'dsto'run into a tank from which it m'a'yfbel returned. The bottom of this channel isiat a lower level than the bottom of the passageway so vas to prevent the liquids from ilowing out through this passageway. V.

The accompanying drawings illustrate as an example a method 'of construction of such a framework. In the drawings:r f

Fig. 1 is a vertical longitudinal :section taken through line I--I of the plan in Fig. 2.

Fig. 2 is a plan corresponding to the above.

Fig. 3 is a cross-section drawn through the line III-III 0f Fig. 2.

Fig, 4 is a plan View taken from underneath.

As will be seen in Fig. 3 of these drawings the space included between the two longitudinal slides I and 2 is clear and two inclined surface portions 3, 4 are provided in this area. In Eig. 1,

the slope of these inclined surface portions is clearly visible. At the lowest part of these inclined surface portions there are discharge .openings 5, 6 discharging intoy passageway/s 1 and 8, that lead to the side face I4 of the framework.

Within the frame there is a slightly sloping channel 9 that leads into a container IIl that acts as a tank for the liquid used for sprinkling the workpiece end the tool. A screen I5 is iitted at the exit end of this channel 9.

It will be observed that the bottom of the channel 9 is on a lower level than the bottom of the passageways 'I and 8.

The container I0 is extended at I6 beyond the side face I4 of the framework. In this extension is placed a motor-pump set I2 that is equipped with an inspection gate I3.

The assembly of the frame is in the shape of a strongly ribbed caisson, as shown in the bottom view of Fig. 4, so as to give the least chance to distortion.

When the machine-tool is at work, the filings and sprinkling liquids fall on the inclined surface portions 3 and 4. the discharge openings 5, 6, drop into the inclined channel 9 and after being filtered through the screen I5 ilow into lthe container I6. Since' the bottom of the channel 9 is on a lower level than the removal openings leading into theV passageways I., 8, the liquids used for sprinkling'cannot flow through these removalopenings. The liquids are returned` from the container III bythe. pump I2 that delivers them into the sprinkling- The filings drop gradually on tothe inclined surface portions 3 and 4 and fall through the discharge openings 5 and 6 and are Aremoved through the passageways 'I and 8', e. g. with rakes.

When the channel Sneeds cleaning, the screen I5,v is removed and a rake is pushed through a port I I, cut in the side of the framework.

What I claim is:

r1. In a boring machine and the like machine tool the combination of' a frame, two slidew'ays on said frame, hoppers provided between; the slideways at a level underneath sameadapted to receive the shavings and the liquid falling 'oi the work, passageways transverse to said slideways into which said hoppers open and directed downwardly towards the outside of the frame, a sloping channel arranged tranversally of said passageways, the bottom of the channel lying at a lower level than the corresponding ends of the transversal passageways opening therein. a screen placed at the end of said sloping channel, and a. tank to receive the oil which has been ltered by said screen.

2. In a boring machine and the like machine tool the combination of a frame, two slideways on said frame. hoppers provided between the slideways at a level underneath same adapted to receive the shavings and the liquid falling on the work, passageways transverse to said slideways into which said hoppers open and directed downwardly towards the outside of the frame, a sloping channel arranged transversally of said passageways, the bottom of the channel lying at a lower level than the corresponding ends of the transversal passageways, means for returning the liquid collected in the container on to the work, a screen placed at the end of said sloping channel, and a tank to receive the oil which has been ltered by said screen.

3. In a boring machine and the like machine tool the combination of a reinforced lundeformable ribbed frame. two slideways on said frame,

The liquids `flow out through.

dinal frame under said upper surface thereof; a

' container connected to said sloping channel at and a tank to receive the oil which has been filtered by said screen.

4. In a machine tool in combination a long'itudinal frame having side faces and an` upper' l surface; an inclined surface portion forming partof said upper surface of said longitudinal frame; a sloping channel arranged within said longitudinal frame under said upper surface thereof; a

discharge opening at the lowermost point of SaidI inclined surface portion of said upper surface leading into said sloping channel; and a passageway within saidlongitudinal. frame below said upper surface thereof leading from one side face of saidv frame into said sloping channel at a point located underiysaid discharge opening and above the bottom of said sloping channel. 5. In a machine tool in combination a longi tudinal. frame having side faces and an upper surface; an inclined surface portionY forming part of said upper surface of said longitudinal frame;- a sloping channel arranged-within said longitu dinal frame under said upper `surface thereof; a discharge opening at the lowermost point of said incl-ined` surface portion 4of said upper surface leading into said sloping channel;A a removal the lower end thereof; a discharge opening at the lowermost point of said inclined surface portion of said upper'surface leading into said sloping channel arranged within said longitudinal frame under said; upper surface thereof; a removal opening in the wall of "said sloping channel located below said discharge opening and above the bottom of said sloping channel; and a passageway Within said longitudinal frame under l saidY upper surface thereof connecting said re- Irnoval opening with one side face of said frame.

'1. In a machine tool in combination a longitudinal frame having side faces and an upper I, surface; an inclined surface portion forming part ofsaid upper surface of said longitudinal frame; a sloping channel arranged within said longitudinal frame under said upper surface thereof; a discharge opening at the lowerrnost point of said inclined surface portion of said upper surface leading into said sloping channel arranged within said longitudinal frame below said upper surface thereof; and a passageway within said longitudinal frame under said upper surface thereof leading from one side face of said frame into said sloping channel at a point located under said discharge opening and arranged in such a manner as to prevent unintentional flow of oil from said sloping channel through said passageway` MARCEL PGARD.
